no thats not why.. do you have the straight axle or the independent front with the cv shafts if so your cv shafts are most likely bad the shaft is what goes from your front diff. to your hubs makes them turn if not htose then it is your front drive shaft not the big one that goes to the rear wheels the little one..

and the guy with the 04 check your boots on your cvs and might be a bad one that chipped a tooth on the splined shaft that slides into your shaft id get it looked at if i were you shouldnt be making noise unless your tires rub a little ...like i said might be these things if i could crawl under and look id be able to tell you more been through a few cv shafts...

uncle had the same problem with his SUV, took it to the shop and something was messed up forget what it was.

well it is either a wheel bearing or cv shaft or your front drive shaft..

you have a 1990, u have a twin i-beam suspension, the axle doesnt have cv joints, it has u-joints, just like a driveshaft. either your u joint are bad, or it could possibly have a different gear in the front. hightly dout the second on, but im willing to bet yor u-joint in the axles are bad, my truck did the same thing
